Quantum Technology

The Fraunhofer “Attract” Junior Research Group “Quantum-UWBG,” rooted in Leipzig, conducts research on color-center-based quantum technologies in close collaboration with the University of Leipzig. 

Color centers are specifically created in the ultrawide bandgap (UWBG) semiconductor materials and UWBG devices developed by the IISB for power and communication electronics through single-ion implantation, and then functionalized as quantum sensors. These atomic sensors, which can be placed inside devices in a non-invasive manner, enable, for example, the monitoring of current and temperature spikes or the characterization of devices in a much more precise manner. This allows manufacturing processes to be optimized, and the combination of quantum and device technologies make it possible to create entirely new types of applications. 

The methods used and developed in the fields of optical and electrical characterization and single-ion implantation are applicable both along the UWBG semiconductor value chain at the IISB as well as for other solid-state quantum technologies. 

Key topics / Services: 

• Ion implantation with low or medium flux in the keV energy range for the generation of color centers and other applications in the field of semiconductor and quantum technologies 
• Characterization of the photoluminescence of individual color centers and ensembles using laser scanning confocal microscopy in various materials (e.g., diamond, GaN, AlN) 
• Development of ion implantation processes for the optimized formation of color centers in different materials
